the front belt drum 5;

The belt 11 is of such a length as to en- 7 able its upper run which isdriven by the belt drum 2 in an upward direction, to take.

the form of two transversely extending parallel troughs l3 and l4,'intowhich branning or cleaning material is'placed. The lower,

or forward trough 1 3 isformed between the forward belt drum; 5 and thebelt support- Ting roller9 and the upper or' rearward trough 1 1 isformed between thesaid roller *9 and the rear belt drum 2.

In order to form these troughs 13 and 14 in the belt 11, there areprovided above the belt two transverse spindles 15 and; 16, fixed attheir opposite ends inupwardly extend ley s of each pairare arrangednear the op-' posite endsiof the spindles in such .a posiof the beltllat side edges thereof. Move tion that they bear upon the upper surfacement along the spindles of-the-idle pulleys 18 is prevented in anysuitable manner, as for instance, by providing collars 19-fixed tothespindles on the opposite sides of the said idle pulleys, see Figure3. 1

The spindle 15 is located in such a post 'tion and the wheels or idlepulleys 18 there on, are of sucha diameter that the said pul- I leysdepress thebelt 11 between the forward periphery of guide wheels .oridle bears upon this thickened portion.

belt drum 5 and the supporting roller 9, thereby forming the forwardtrough 13,

,while the spindle 16 and the wheels or idle pulleys 18 thereon,are soarranged and constructed that the said pulleys causethe belt to take theform of the rear trough 1/1. H

Y The outer surface ofthe belt 11 is, at its thicknesses showngat "11Figure 3 and the pulleys 18 Each wheel 18; is formed on its 'inner'edgewith a peripheral flange 20 against which the inner edge of the.thickened portion 11 bears, so that any bellying' of theibeltbebranning-or cleaning material contained in I thetroughis preventedj Toform-a closure to the opposite ends of the troughs at'the sides of thebelt 11,}th'e inner sides of the wheelsor idle pulleys 18 areeachdisklike, with apertures formed d therein to decrease its weight,but having v afisubstantiallyc inwardly extending radial,

- I flange or surface 21 which prevents blfilP' :ni-ng o cleaningmaterial from falling out of the endsofthetroughs.

frame 22 comprising two Arranged above the belt 11 and preferablyremovably supported by the spindles 15 and 16 and bet veen the guidewheels or idle pulleys 18, is a metal longitudinal side. membersconnected at their forward and rearward ends by transverse round rods 23and 2 1 respectively. Similar rods 25 and 26 are arranged towards thecentre of the said side members.,Depending from each side member are twolugs or brackets 27 forked at, their-lower ends and adapted to straddlethe spindles 15 and 16. The collars 19 fixed to the spindles at theinner sides of the pulleys 18, form stops to the movement oflthebrackets 27 along the said spindles and thus retain the frame centrallybetween therguide wheels or idle pulleys 18.

28, 29, and 31 are'pressure rollers which are adapted to zbea'r lightlyon the surface of .the belt 11. The roller 28 is adapted to bear on thebelt '11 somewhat rearwardly of the axis of the lower or forward beltdrum 5 and'the roller29 is adapted to bear in a similar manner on thebelt, at a position somewhat rearwardly of the aris of the beltsupporting rolle 9. r 1

Theserollers 28. and 29 are each revolubly carried at .theiroppositeendsin bear ings at the lower ends'ofarms 32. The upper ends of thesearms are hooked, as at 33, by which means the arms carrying therolle 28are freely suspended from the transverse rod 23 of the frame 22 and thearms carrying the roller 29 are likewise suspended from the transverserod 26, the arrangement being such that the weight of the rollers andtheir supporting armscauses the said rollers to'bear upon the belt 11atthe desired part. 1

The rollers 30yand 31 are similarly 'suspended from the transverse rods25 and 24L respectively, by means ofhooks 34 connected to arms 35. Inthese instances the arms 35 extend above their point-of suspension andare :bent forwardly. The arms offeach pairare connected, at theirforward ends by a transverserod or bar 36 which forms a counterweight toforce the roller in a rearward-direction onto the belt 11, thec'ounterweight being preferably adjustable on the arms 35 so that thepressure of the rollers u 30 and 31 on the belt 11 can be regulated.tween its sides, due to the weight of the India rubber or like resilientrings 37 and 31. T Thesaid, rings project beyond the periphery. oftheroller and, are adapted to I bear upon the surface-of the plate andthus prevent. the scratching of the surface theref a 38 and 39 are plate-guiding grids which are fixedon to the spindles 25 and 26 respectivelyand are adapted to.reverse the plate side for side during its traversethrough the sprocket WheelAO: on the spindle {60f thee'belt drum -5,being preferably-employed to feed the :pl'ates on: to thergbelt:Atthisipart; the" belt-l1 assumes a-- substantiallyshorizontal:T015:
